The Tokico Emergency Shutoff Valve is a safety disaster prevention device required under the High Pressure Gas Safety Law and Fire Defense Law. It is designed to urgently shut off or open pipelines carrying various fluids, preventing secondary disasters in industrial facilities.
The MB series uses a CO₂ gas cartridge as its drive source, delivering high initial torque for reliable valve actuation. A ball valve mechanism ensures smooth movement and tight sealing. The valve can be triggered by different signals — electric, line pressure, or seismic — making it adaptable to comprehensive disaster prevention systems.
This valve is most suitable for city gas, natural gas, and LP gas applications, and can be integrated with sensors such as gas leak detectors and seismoscopes for automated safety response.
